The closing years of the eighteenth century marked the beginning of a great and far-reaching industrial revolution. The introduction of new mechanical inventions enormously increased the productive powers of England. In 1770 Hargreaves patented his "spinning jenny," and in the following year Arkwright invented his "water frame," a patent spinning machine which derived its name from the fact that it was worked by water power. Later, in 1779, Crompton invented the "mule," which was really a combination of the principles of both machines. This was a long step forward, and greatly facilitated the spinning of the raw material into yarn. The invention was, in fact, a revolution in itself. Like so many other great inventors, Crompton died in poverty. Even now, however, the actual weaving had to be done by hand. Not until 1785, when Dr. Cartwright, a parson, invented a "power loom," was it deemed possible to weave by machinery. Cartwright's invention, coming in the same year as the general introduction of Watt's steam engine in the cotton industry, made the industrial revolution. Had the revolution come slowly, had the inventors of the new industrial processes been able to accomplish that, it is most probable that much of the misery of the period would have been avoided. As it was, terrible poverty and hardship attended the birth of the new industrial order. Owing to the expense of introducing the machines, and the impossibility of competing with them by the old methods of production, the small manufacturers themselves were forced to the wall, and their misery, compelling them to become wage-workers in competition with other already far too numerous wage-workers, added greatly to the woe of the time. William Morris's fine lines, written a hundred years later, express vividly what many a manufacturer must have felt at that time:-- "Fast and faster our iron master, The thing we made, forever drives."
